Show N/A for for particular combination and show value for specific combination only

Question

I have following cube Structure:
Measure
     Value
DimTime
    Fiscal Month
DimTable
   Table Name
   Row Name
   Column Name
DimGeography
   GeographyLevelName
   GeographyName
Questions:
1) I want to show N/A when only measure value is selected
2) I want to show N/A when I slice measure value w.r.t to GeographyLevelName, GeographyName, FiscalMonth, TableName, Row Name
3) I want to show measure value for this combination only FiscalMonth, GeographyLevelName, GeographyName, FiscalMonth, TableName, Row Name, Column Name and Value (measure)
Option tried:
I used Scope to achieve this but not able to do for all scenarios:
SCOPE(Measure.[Value]);
     SCOPE(Root());
           SCOPE(Measure.[Value], DimTime.[Fiscal Month].MEMBERS, DimTable.[Table Name].MEMBERS,
                  DimTable.[Row Name].MEMBERS, DimTable.[Column Name].MEMBERS,
                  DimGeography.[GeographyLevelName].MEMBERS,   
                  DimGeography.[GeographyName].MEMBERS);
                  THIS = 'N/A';
        END SCOPE;
     END SCOPE;
END SCOPE;
Any suggestion is appreciated :) :D
